build regenerating SkJumper stages into GN
I _think_ this makes it so changes to _stages.cpp or _lowp.cpp get
noticed, regenerated, and baked into Skia all in the same Ninja
invocation.
Now you just need to set up the tools we use in GN:
skia_jumper_clang = ...
skia_jumper_objdump = ...
skia_jumper_ccache = ...
